超大直径泥水盾构隧道综合施工技术控制

Integrated Technical Control of Tunneling with a Super-large Diameter Slurry Shield

针对南京长江隧道复杂的地质条件,结合已施工地段的特点,对超大直径泥水盾构的掘进参数设定、掘进姿态控制、泥水管理、同步注浆、管片拼装、同步施工等综合施工技术进行较系统的阐述。

Nanjing Yangtze River tunnel ranks the second in the world in the kind of shield tunnels with large diameter while the geological conditions of the tunnel are most complex. The paper describes in detail the selection of excavation parameters, control of shield postures, management of slurry, synchronic injection, segment erection and synchronic construction etc., with the complex geological conditions and the features of the built sections of the tunnel taken into account.
